MetaMask Login — Secure Sign-In & Restore Guide

This practical guide explains how to perform a secure MetaMask login on desktop and mobile, how to restore your wallet using the recovery phrase, how to troubleshoot common login problems, and which security steps prevent phishing and theft. These steps assume you use the official MetaMask extension or mobile app and that you keep your seed phrase offline and secret.

How to log in to MetaMask (extension & mobile)

MetaMask runs as a browser extension and a mobile app. Login always happens by unlocking the wallet locally — with a password, PIN, or biometric — or by importing the wallet using the recovery phrase on a new device.

Browser extension — step-by-step

  1. Install the official extension: Go to the official site and follow the link to your browser’s web store. Verify the publisher and reviews.
  2. Open and unlock: Click the extension icon and enter your password to unlock the wallet. If creating a new wallet, follow onboarding and write down the 12-word seed phrase safely.
  3. Auto-lock and session policy: Set an auto-lock timeout and lock the extension when idle on shared machines.

Mobile app — sign-in steps

  1. Install from official store: Use the App Store / Google Play entry from the official site.
  2. Unlock or restore: Use a PIN/biometric to unlock, or import using the seed phrase via the 'Import using seed phrase' option.
  3. Enable biometrics for convenience: Use device biometrics for quick unlocking while keeping the seed offline.
Security reminder: Only enter the recovery phrase into MetaMask’s restore screens — never into websites, emails, chats, or third-party apps.

Restore MetaMask using your recovery phrase

Restoring with your 12-word phrase is the only practical way to regain control if you lose the extension password but still have the seed. It is therefore critical to store the seed securely.

Restore steps (extension)

  1. Install the official extension and choose "Import wallet".
  2. Enter your 12-word seed in order and set a new strong password.
  3. Verify recovered accounts and custom tokens after restoring.

Restore steps (mobile)

Install app → choose 'Import using seed phrase' → enter words in order → complete setup and enable PIN/biometrics.

If you do not have the seed phrase, technical recovery is not possible — reinforce why offline backups matter.

Security best practices

  • Download only from official sources: Bookmark the official site and avoid search results for downloads.
  • Never share your seed: Legitimate support never asks for your 12-word phrase.
  • Use hardware wallets: For meaningful funds, connect MetaMask to a Ledger or Trezor to keep keys offline.
  • Limit approvals: When dApps request token allowances, set minimal allowances and review approvals regularly.
  • Keep software updated: Browser, OS and MetaMask versions should be current to minimize vulnerabilities.

Troubleshooting common login issues

Forgot password but have seed

Reinstall the extension and restore using your seed phrase. Always confirm seed existence before uninstalling.

Extension not responding

Try restarting the browser, disabling conflicting extensions, or using a fresh browser profile. Reinstall if needed, restoring with seed afterward.

Missing tokens after restore

Add custom token contract addresses manually — balances are on-chain even if UI does not list them automatically.

FAQ

Can MetaMask support recover my account?

MetaMask cannot recover your seed. Support can help with app issues, but the seed is the only way to fully restore wallet access.

Is MetaMask safe for DeFi?

Yes — when used with caution: use hardware wallets for large positions, verify smart contracts, and limit token approvals.
